Whois

The WHOIS service provides public access to information
about a domain name and its Administrator. It lets you know:
— when the domain was registered;
— when does the domain registration period ends;
— which registrar has a web address on the service;
— some data about the domain administrator, if he do not use the personal data hiding service.
The last item applies only to owners of international domains. The data of domain Administrators in th .RU and .РФ zones is hidden by default.

Enter the domain, IP-address or name of the Registrar and get full information!
